Lupinus plant named &#39;LSTYE05-0&#39;

ABSTRACT

A new and distinct Lupinus cultivar named ‘LSTYE05-0’ is disclosed, characterized by distinctive clear yellow flowers. Plants uniquely bloom under both short day and long day conditions without vernalization. The new cultivar is a Lupinus, suitable for ornamental purposes.

Latin name of the genus and species: Lupinus hybrida.

Variety denomination: ‘LSTYE05-0’.

BACKGROUND OF THE INVENTION

new variety, hereinafter referred to as ‘LSTYE05-0’, was discovered as part of a planned breeding program. The intent of the breeding program was to develop Lupine hybrids for commercial ornamental applications.

SUMMARY OF THE INVENTION

The cultivar ‘LSTYE05-0’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype. The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘LSTYE05-0’ These characteristics in combination distinguish ‘LSTYE05-0’ as a new and distinct Lupinus cultivar:

1. Plants uniquely bloom under both short day and long day conditions without vernalization.

2. Clear yellow flower coloration.

COMPARISON TO PARENT VARIETY

‘LSTYE05-0’ is similar in most horticultural characteristics to the seed parent variety. Plants of the new cultivar ‘LSTYE05-0’ however, differ in the following characteristics:

1. The new variety has a different flower color.

‘LSTYE05-0’ is similar in most horticultural characteristics to the pollen parent variety. Plants of the new cultivar ‘LSTYE05-0’ however, differ in the following characteristics:

1. The new variety has a different flower color.

COMMERCIAL COMPARISON

‘LSTYE05-0’ can be compared to the commercial variety Lupinus ‘Saffron’, unpatented. Plants of the new cultivar ‘LSTYE05-0’ are similar to plants of ‘Saffron’ in most horticultural characteristics, however, plants of the new cultivar ‘LSTYE05-0’ differ in the following:

1. Flower color of the new variety is a brighter yellow. 2. Plants of the new variety are shorter and sturdier. 3. Plants of the new variety will begin flowering without vernalization, as required by this comparator.

‘LSTYE05-0’ can be compared to the commercial variety Lupinus ‘West Country Desert Sun’ unpatented. Plants of the new cultivar ‘LSTYE05-0’ are similar to plants of ‘West Country Desert Sun’ in most horticultural characteristics, however, plants of the new cultivar ‘LSTYE05-0’ differ in the following:

1. Flower color of the new variety is brighter yellow, with a yellow banner, this comparator has a yellow flower with a cream colored banner. 2. Plants of the new variety are shorter and sturdier. 3. Plants of the new variety will begin flowering without vernalization, as required by this comparator.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in illustrates in full color a typical plant of ‘LSTYE05-0’ grown in a greenhouse in Santa Paula, Calif. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
